More than invoicing. A lot more.
Mint Books does the heavy lifting that other apps leave to you – reading receipts, chasing payments, calculating CIS and filing with HMRC.
AI receipt scanning
Photograph any receipt, Amazon order or supplier invoice. AI pulls out the vendor, amount, date and VAT and files it in the right HMRC category.
Quotes clients sign online
Send a quote, the client accepts with a digital signature (name, IP and device recorded), and you convert it to an invoice in one click.
Invoices that chase themselves
Send by email or WhatsApp, see when it's opened, take card payments via Stripe, and let automatic reminders chase late payers.
HMRC, handled
9-box VAT return calculated for you and submitted direct to HMRC via Making Tax Digital. Standard, Cash and Flat Rate schemes. CIS built in.
Professional invoicing
Branded invoices, auto-numbering, batch sending, credit notes, late fees and multi-currency.
Reports your accountant wants
P&L, balance sheet, cash flow, aged debtors & creditors, trial balance and statutory accounts.
CIS & construction
Automatic labour/materials split, 20% or 30% deductions, VAT reverse charge and UTR tracking.
Time tracking
Log billable hours per project, set rates, and turn time entries into invoice lines in one click.
Projects & job costing
Track budgets, assign costs, link invoices and expenses, and see profit per job.
Automations
Custom workflows with triggers and actions – auto-categorise, auto-tag, auto-remind, with full logs.
Full double-entry bookkeeping
Chart of accounts, journal entries, opening balances and period locks for accountants and power users.
