Intuit has agreed to buy Sequence, a company that calculates bills for businesses charging customers by usage, user accounts or project milestones. The October 15 agreement would give QuickBooks’ owner a business built around calculating and collecting charges under negotiated contracts.
The acquisition has not closed. Intuit said it would continue supporting Sequence customers and develop an integrated offering in the coming months. It disclosed neither the purchase price nor what customers would pay for the combined service.
Intuit’s business-software operation already produces billions of dollars in annual sales. In its August 25 earnings report, Intuit said Global Business Solutions generated $12.9 billion in fiscal 2026, up 16 percent from the previous year. Its Online Ecosystem, part of that segment, produced $9.9 billion, up 19 percent. The fiscal year ended July 31. These are revenues recorded before the agreement to acquire Sequence. They include Mailchimp, which Intuit began managing separately on August 1 and will report as a separate segment in fiscal 2027.
The company’s annual report, filed September 9, gives a more detailed view of that growth. Average revenue per paying customer in the Online Ecosystem rose 15 percent during fiscal 2026, while the paying-customer count on July 31 was 3 percent higher than a year earlier. The count spans QuickBooks Online, QuickBooks Time, Mailchimp and standalone services. It is not a count of Enterprise Suite customers, and the revenue average covers a year rather than a single date.
QuickBooks Online Accounting revenue reached $5.051 billion, up 23 percent, according to the filing. Intuit attributed that increase to higher effective prices, customer growth and changes in the mix of products sold. Payments revenue increased $257 million, with Intuit citing more customers and higher payment volume per customer among the causes. The deal would add billing based on negotiated contracts to Intuit’s accounting and payments products.
Sequence already connects to QuickBooks, as well as Xero and NetSuite. It can send invoices into accounting systems and exchange information with sales software and data warehouses. Intuit is buying a billing company that works across those systems, including rival accounting products, rather than simply arranging a first connection between two applications.
Ashley Still, who leads Intuit’s small-business and midmarket group, described complicated billing as a reason growing companies choose a larger business-management system. The acquisition would help Intuit serve software and professional-services companies whose charges depend on changing activity or the completion of agreed work.
Intuit sells its own larger system, Enterprise Suite, for companies managing more complicated finances. Such products are often called enterprise resource planning systems, or ERPs. Intuit’s pricing page offers a negotiated bundle based on a company’s needs, users and chosen products. It does not publish a single subscription price that a prospective buyer can apply to every business.
Sequence’s billing product shows why a separate application can be necessary even when a company already has accounting software. It supports annual contracts with staged price increases, minimum spending commitments, charges for user accounts and fees based on consumption. A company’s sales agreement can combine several of those terms, with discounts or changes taking effect on different dates.
Its advertised functions include recalculating charges after a contract amendment, accounting for a partial billing period and issuing credit notes when a contract ends early. Those functions affect both sides of a sale. The seller has to collect what the agreement permits; its customer needs reductions and credits reflected when the agreement changes.
Sequence advertises its standalone Growth plan at $799 a month for startups with less than $1 million in annual revenue. Paying that monthly rate for 12 months would cost $9,588. This is an annual calculation from the advertised monthly charge, not a separately advertised annual plan or a price for the future Intuit offering.
Growth lists invoicing, usage measurement, flexible pricing, custom contract terms and connections to accounting and sales systems. A quote builder and custom reporting dashboard are optional additions. Core, aimed at companies with $1 million to $10 million in annual revenue, and Scale, for those above $10 million, require individual quotes.
Sequence says larger customers’ monthly platform fees depend on projected billed revenue and required features. Scale includes migration services and dedicated onboarding. Consequently, the public entry price does not establish what a larger finance department would spend to move its billing, add features and operate the service.
Usage-based bills require records of customer activity. Sequence’s metering product lets businesses send records through a programming interface, which lets their software transfer data automatically, or bring them in from a data warehouse, a central store of business records. They can filter those records and define several billable measurements from the same kind of activity. That turns information about product use into quantities an invoice can price.
The company says customers can track invoice totals during a month and submit usage after month-end, then recalculate invoices in bulk. The final charge therefore depends on when activity arrives as well as how a contract prices it. A billing service can perform the calculation, but it still needs the business supplying that activity to record it.
The published billing instructions make the financial choices more concrete. A billing schedule can contain separate contract phases, discounts, minimum charges and credit grants, or allowances applied against charges. The documented fields also specify when a period begins and ends and whether invoices should issue automatically. Those settings let finance staff specify the billing arrangement and how much of it should proceed automatically.
An October 2025 case study published by Sequence describes Arch, which helps investors manage private-market investments, tracking daily changes in paid accounts. Its arrangements combined annual or semiannual billing with quarterly adjustments for additional use.
Sequence says Arch used its programming interface to update account counts daily and automate the resulting charges. The case describes both charges and credits when customers add or remove accounts. Collecting more money can therefore mean billing additional activity under an existing contract, rather than raising the contract’s stated price.
Arch also kept different payment arrangements for different customers: smaller businesses paid through Stripe, while larger ones used bank transfers, according to the case study. Changing the billing application did not require a single payment method for every customer.
Sequence’s explanation of its AI is more specific than the acquisition announcement’s broad description. In a December 16, 2025 financing post, it said AI handled jobs such as reading contract terms, reviewing invoices and following up on payments. It said the billing arithmetic remained deterministic: the same defined inputs and rules produce the same calculation.
Under that design, an AI tool might extract a rate from a contract, while a billing engine multiplies that rate by recorded use. Finance staff would still review exceptions and approve complex situations, according to Sequence. Interpreting an agreement and calculating a bill are separate tasks within the process Sequence describes.
That financing announcement reported a $20 million Series A, bringing total funding to $38 million. It named finance teams at companies including incident.io and Bridge among its customers. 645 Ventures led the round, joined by investors including a16z, Firstminute Capital and Passion Capital.
The next announced step is an integrated offering after the acquisition closes. Until Intuit publishes its scope and price, businesses can assess Sequence’s existing service and advertised charges, but cannot calculate the cost of the combined product.
