Last reviewed: July 10, 2026
Invoice2go is a web and mobile billing service that connects several stages of a small business transaction: preparing an estimate, issuing an invoice, collecting a customer payment, tracking the balance, and passing financial information into other records. The central idea is easy to miss. An invoice, a successful payment, and a bank deposit are three separate events, even when one application displays all of them.
What Invoice2go actually does
Invoice2go is designed primarily for small businesses, independent contractors, freelancers, and consultants that need to prepare estimates and invoices away from a traditional finance office. Its product includes invoices, estimates, clients, items, expenses, projects, reports, time entries, payment options, credit memos, and purchase orders.
Calling it an “invoice maker” is accurate but incomplete. A plain template produces a document. Invoice2go also keeps that document connected to its customer, status, payment history, reminders, related project, and other business records.
The workflow resembles a parcel moving through several labeled depots. An estimate can become an invoice; the invoice can be sent and opened; a customer can authorize payment; the processor can clear the transaction; the resulting money can later be transferred to a bank. Reaching one depot does not mean the parcel has reached the last one.
This framing matters because business owners often use “paid” to describe several different moments. A customer may say that payment was submitted, Invoice2go may show the transaction as pending, and the bank may not yet have posted the eventual transfer. All three statements can be true at once.
Stage one: proposed work becomes billable work
Many Invoice2go transactions begin with an estimate rather than an invoice. The estimate describes proposed products or services before the amount becomes a formal request for payment.
A residential painter, for example, might prepare an estimate containing labor, paint, surface preparation, and a proposed completion schedule. A freelance designer might quote a fixed project price with a deposit request. A mobile repair technician might use saved items for labor hours and replacement parts.
After the customer accepts the work, the estimate can be converted into an invoice. This preserves the client and line-item information while moving the transaction into the billing stage. An approval by itself does not always mean money has changed hands, and a manually marked approval records a status chosen by the business rather than proving that the customer personally completed an online approval action.
Invoice2go also lets time entries become billable material. A user can record when work starts and stops, attach notes, retain the entry as unbilled time, or add it to an invoice.
The common confusion here is estimate versus receivable. An estimate describes a possible transaction. An invoice states that the business is requesting payment for an amount associated with supplied or agreed work.
Stage two: an invoice becomes an amount receivable
Creating an invoice establishes the bill inside the software, but it does not prove that the customer received or reviewed it.
Invoice2go uses document statuses to show movement through the communication process. Unsent means the invoice has not been delivered through the recorded workflow. Sent means it was emailed or messaged but has not been opened. Opened means the customer selected the invoice-viewing control. Overdue means the due date has passed, while Fully Paid means the full balance has been recorded as paid.
Those labels are operational markers, not conclusions about the customer’s intentions. Opened does not mean accepted. Sent does not guarantee that the recipient noticed the message. Overdue does not explain whether the delay came from a dispute, an approval process, an incorrect address, or ordinary late payment.
Invoice2go can also create client statements that group multiple invoices for one customer. When the necessary payment settings are enabled, the customer can select several unpaid invoices from a statement and submit one payment. Invoices already marked paid remain visible but cannot be selected again.
This matters more for a small commercial contractor with several open jobs than for a freelancer who normally has one invoice per customer. The statement represents the wider customer balance, while each underlying invoice keeps its own number, status, amount, and transaction history.
Stage three: the customer authorizes a payment
An invoice is not itself a payment instrument. It becomes payable online when the business enables a supported payment option and the customer receives a Pay now control on the document.
At that point, Invoice2go acts as the customer-facing billing layer, while the configured payment provider handles the financial transaction. The customer chooses an available method, submits the payment through the portal, and the transaction is associated with the relevant invoice. Availability varies by account, provider, and region.
The distinction can be illustrated with a $1,200 landscaping invoice. The customer’s approval of a card charge is the payment event. The invoice’s outstanding balance may then be updated inside Invoice2go. The eventual transfer to the landscaping company’s bank is a later settlement event.
Outside payments follow a different path. When a customer pays by cash, check, or another method not automatically processed through the invoice portal, the business can record the full or partial payment manually. That record updates the invoice, but Invoice2go did not process the underlying exchange merely because it was entered into the transaction history.
Payment-card transactions also sit within a larger security system. The PCI Security Standards Council describes PCI DSS as a baseline of technical and operational requirements intended to protect payment account data. Invoice2go’s documentation identifies Stripe as a PCI Service Provider Level 1 processor for supported card-payment arrangements.
Using a hosted payment process can reduce the amount of payment information handled directly by the business, though specific compliance responsibilities depend on the merchant’s full setup.
Stage four: processing becomes a bank payout
This is where the language becomes slippery.
A customer payment may be successful from the customer’s perspective while remaining pending inside the processing system. Invoice2go says Invoice2go Money Card Payments usually take one to three business days from payment to availability in the linked bank account. It also says the transaction may remain pending while processing, which usually takes two business days. Transfers are affected by processing cutoffs, weekends, and bank holidays.
ACH timing follows a different pattern. Invoice2go states that funds accepted through Invoice2go Money typically clear in two to three business days and remain pending until successful; transactions initiated after the listed cutoff can require another day.
Stripe and PayPal follow their own settlement routes. Invoice2go notes that bank posting can add time after Stripe has verified and sent a payment, while a standard PayPal-to-bank transfer is described as usually taking three to five business days, subject to holds and financial-institution timing.
These ranges should not be blended into one universal Invoice2go payout promise. The method selected by the customer, the processor attached to the account, transaction review, the bank, weekends, holidays, and the country can all affect the result.
A useful vocabulary separates four moments:
- Invoice issued: The business requests payment.
- Payment submitted: The customer authorizes a method.
- Payment processed: The provider clears or settles the transaction.
- Payout posted: The business can see the transferred funds at its financial institution.
The common confusion is payment versus liquidity. A paid invoice can improve the company’s accounts-receivable picture before the money becomes available for payroll, materials, or other spending.
Why statuses and reminders sit between billing and collection
Invoice2go’s reminders operate on invoice status and due dates. Its default schedule sends notices three days before the due date, on the due date, three days after it, and seven days after it, provided the invoice has not been fully paid. The schedule can be changed, and reminders can be disabled for an individual document.
That feature represents a small form of accounts-receivable automation. It does not make a collection decision on behalf of the business. Instead, the system observes that a balance remains open at a scheduled point and sends the configured communication.
A partially paid invoice remains relevant because money is still owed. For example, a contractor may receive a $500 deposit on a $2,000 invoice. The transaction reduces the balance, but the document should not be treated as fully paid while $1,500 remains outstanding.
Recurring invoices work differently from automatic collection. Invoice2go can prepare a new invoice weekly, every two weeks, or monthly, depending on the plan and selected schedule. The resulting document is presented for review and is not sent automatically without the user’s approval.
That review step separates recurring document creation from autopay. A monthly invoice can be generated repeatedly without giving the software permission to charge the customer automatically.
Who uses each side of Invoice2go?
The business is the primary subscriber. It creates the account, stores its clients and items, prepares documents, controls payment options, and reviews reports.
The customer has a narrower role. The customer receives an estimate, invoice, statement, or payment request and interacts with the document supplied by the business. The recipient does not need to operate the business’s main Invoice2go workspace merely to open a payable invoice.
A bookkeeper or staff member can occupy a third role. Invoice2go supports team access, though permissions and plan availability determine which information a team member can see or change. The owner may use the mobile application at job sites while office staff monitor open invoices and reporting from the web application.
This division is especially relevant for tradespeople and professional services. The person who performs the work may initiate the estimate, while somebody else confirms payment, exports records, or prepares information for the accountant.
Invoice2go versus a payment processor and accounting system
Invoice2go touches both categories without being identical to either.
A payment processor moves and settles electronic transactions. It handles authorization, processing, disputes, and the transfer path attached to a supported payment method. Invoice2go places that capability inside the invoice experience so the customer can move from reading a bill to paying it.
An accounting system maintains the broader books of the business. That can include ledgers, account reconciliation, assets, liabilities, income and expense classifications, financial statements, and tax-related records.
Invoice2go includes expenses, reports, cash-flow views, projects, and transaction histories, so it covers more than document design. Yet it also offers integrations in categories such as accounting, CRM, spreadsheets, and cloud storage.
Its Xero integration shows the boundary clearly. Invoice2go says sent invoices can sync with the Xero sales account along with client and tax information. The invoice begins in the billing system, while the connected accounting product receives information for the books.
A processor answers, “How did the customer pay?” Invoice2go answers, “Which customer and invoice does this payment belong to?” Accounting software answers, “How should the transaction affect the company’s financial records?”
Some products perform pieces of all three jobs. The categories remain useful because they explain why a figure can appear in one system before it is reconciled in another.
Projects, expenses, and the work behind the invoice
Invoice2go’s project layer groups operational evidence around a job. Projects can hold invoices, estimates, expenses, photos, files, notes, and contact information.
A kitchen installer, for example, might keep the estimate, site photographs, supplier expense, customer contact, and final invoice under one project. A consultant may group time entries, notes, and invoices by engagement. A property-maintenance business may associate several visits and expenses with one client project.
Expenses can also be divided among projects. Invoice2go states that one expense added to multiple projects is split evenly; a $100 expense attached to two projects is shown as $50 for each. That feature is currently documented for iOS and the web.
This is operational allocation, though not necessarily a complete cost-accounting model. A growing business may need more detailed treatment of overhead, inventory, depreciation, or labor burden than an invoice-centered project view provides.
What Invoice2go records mean for taxes and bookkeeping
Invoice2go records can support the financial history of a small business, but the application should not be mistaken for the entire evidentiary record.
The Internal Revenue Service says a business’s recordkeeping system should clearly show income and expenses, while supporting documents arise from purchases, sales, payroll, and other transactions. IRS Publication 583 lists identifying the source of receipts, tracking deductible expenses, preparing financial statements, and supporting tax-return entries among the reasons records are kept.
An invoice shows that the business billed an amount. A processor record can show that an electronic payment occurred. A bank statement can show when funds were deposited. A receipt can support an expense. Together, those records give a fuller account than any single document.
Invoice2go allows company data such as invoices, estimates, credit memos, purchase orders, expenses, clients, items, time tracking, and appointments to be exported as CSV data from the web version.
The limit is important: structured export data is not automatically the same as a permanent archive of every original document or every record required for tax, contractual, or regulatory purposes. IRS retention periods depend on what the record proves and the relevant tax circumstances.
Why BILL acquired Invoice2go
BILL completed its acquisition of Invoice2go on September 1, 2021, for approximately $625 million in stock and cash. BILL described the purchase as an investment in accounts-receivable capabilities for small businesses.
That history reinforces Invoice2go’s market position. The product begins with the money a business expects to receive: estimates, invoices, customer payment options, reminders, and receivables-related records. BILL’s wider platform addresses a broader range of financial operations.
Invoice2go remained a distinct invoicing product after the acquisition. The relationship provides context for the product category, rather than making every Invoice2go account equivalent to the full BILL platform.
Invoice2go FAQ
Is Invoice2go a payment processor?
Not by itself. Invoice2go provides the invoice and payment experience while supported providers process the underlying electronic transactions.
Is Invoice2go accounting software?
It contains financial tools such as expenses, reports, projects, and payment histories, but its main role is invoicing and accounts receivable. Its accounting integrations show that many businesses use it alongside a wider bookkeeping system.
Does an invoice mean the customer has paid?
No. An invoice is a request for payment. Its status can remain Unsent, Sent, Opened, Overdue, partially paid, or Fully Paid as the transaction progresses.
Does “paid” mean the money is already in the bank?
Not necessarily. The customer’s payment may need to be processed and transferred before the financial institution posts it. Invoice2go Money card payments are described as usually becoming available in one to three business days, while other methods follow different schedules.
Are recurring invoices sent automatically?
No. Invoice2go prepares the recurring document and sends an in-app notification, but the invoice remains available for review before the user sends it.
Can Invoice2go track hourly work?
Yes. Time entries can record work periods, notes, clients, and billed or unbilled status before being added to an invoice.
Does a customer need a full Invoice2go business account to pay?
The customer can use the payment option presented on the invoice when online payments are enabled. The business account is operated by the seller, contractor, or service provider.
Are Invoice2go records enough for tax purposes?
They may support income and expense records, but the IRS describes business recordkeeping as a wider system that can include books, receipts, bank evidence, payroll documents, invoices, and other supporting material. The records needed and their retention periods depend on the transaction and tax circumstances.
