How to Build a SaaS for Accountants and Bookkeepers on Bubble.io
Accounting and bookkeeping firms are one of the highest-value SaaS verticals for a Bubble.io product. They have clear workflows, consistent pain points, existing budget for software, and a strong professional network that amplifies word-of-mouth.
Why This Vertical Works
The big accounting software vendors (Xero, QuickBooks, FreeAgent) serve the client’s accounting needs but do not serve the firm’s internal practice management needs; and generic practice management tools do not understand accounting-specific workflows (client onboarding with anti-money-laundering checks, annual accounts production cycles, VAT return scheduling). A Bubble.io product built specifically for a small-to-medium accounting firm’s internal operations — client management, work scheduling, deadline tracking, document collection, team task assignment — fills a gap that no well-funded competitor currently occupies at the boutique firm price point.
What to Build
Client work management and deadline tracker
A system for managing all client work across the firm: which clients have which deadlines (VAT returns, annual accounts, payroll, self-assessment), what the current status is of each piece of work, and who is responsible for completing it. The primary pain point: spreadsheets and email reminders for deadline management that miss deadlines and cause HMRC penalties.
Client onboarding and document collection portal
A structured client onboarding flow that collects the specific information and documents required to take on a new accounting client: anti-money-laundering identity verification, prior year accounts, bank statements, director information, and the engagement letter for e-signature. This replaces the email back-and-forth that typically takes 2-4 weeks per new client onboarding.
Proposal generation tool for accounting services
A branded proposal generator that produces a professional-looking services proposal from a template, with the specific services, pricing, and terms for a specific prospect. This replaces the 2-3 hours a senior accountant currently spends creating a proposal from scratch.
Client portal for document sharing and communication
A secure, branded portal where accounting firm clients can upload documents (receipts, bank statements), download completed work (annual accounts, tax returns), and communicate with their accountant. This reduces the volume of email attachments and unstructured email threads that consume significant admin time.

Q: Do I need to handle Making Tax Digital compliance in a Bubble.io accounting tool?
If the product is designed to submit VAT returns or other digital tax data directly to HMRC on behalf of clients, it must be MTD-compliant and registered as a software provider with HMRC’s MTD programme. A Bubble.io application can integrate with HMRC’s MTD API (a REST API, connectable via the API Connector). For products that manage accounting firm workflows but do not directly submit data to HMRC, MTD compliance is not required.
Q: What is the best way to price an accounting firm SaaS product?
Per-firm pricing (a flat monthly fee per accounting firm, regardless of client count) is SA’s recommended pricing model. Accounting firms know their client count and can plan their software budget accordingly; per-client pricing creates uncertainty and resistance. A price of $99-199/month per accounting firm for a practice management tool is well within the software budget of most boutique firms.
Q: How do I find accounting firms to interview before building?
Professional accounting bodies (ICAEW, ACCA, AAT in the UK; CPA in the US) maintain member directories. LinkedIn searches for ‘Partner at accounting firm’ with location filters generate a targeted list of interview candidates. Accounting-specific communities (AccountingWEB in the UK) have active forums where practice management pain points are regularly discussed.
