The routine work is done before you open the app.
Every morning Sumi runs through the jobs a bookkeeper would do first thing. You decide which ones are on, and you can see everything it did.
Recurring invoices go out
Rent, retainers and subscriptions are created, approved and emailed on the day they are due.
Bank lines match themselves
A transfer for the exact amount owed, from the customer named, is posted against the right invoice.
Customers get a nudge
A polite reminder before the due date, on the day, and while it is overdue, each with a link to the invoice.
Your week, in one email
Invoiced, money in and out, cash in the bank and what needs your attention.
Everything a growing business needs, nothing it doesn’t.
Simple enough for the owner. Proper enough for the accountant.
Invoices that get paid
Your logo, your template, automatic numbering. Share by WhatsApp or email with your bank details, and Sumi chases late payers for you.
Any bank statement
Upload CSV, Excel or PDF from your bank. Sumi suggests what each line is and learns from your choices.
Stock in every branch
Average cost, low-stock alerts and transfers between branches, posted to your books as you sell.
Tax handled
VAT on every sale and purchase, withholding tax on payments, and NRS e-invoicing for Nigerian businesses.
Real double-entry
Journals, credit notes, multiple currencies, departments, lock dates and full financial statements for your accountant.
Payroll with PAYE
Monthly pay runs with PAYE under the 2026 tax rules, pension, NHF and payslips, plus the schedules for your tax office and PFAs.
Ask your books
“What did I spend on fuel last quarter?” Get a straight answer from your own numbers, in plain words.

Sumi Practice, for accountants who keep books on the side.
Keep the books for every client from one login, without a business of your own. Switch between clients in a click, and see what needs doing across all of them.
- One client list. Overdue invoices, bank lines to match and drafts for every client on one page.
- You choose who pays. Your practice pays for a client's books, or the client pays for their own. Decide per client and change it any time.
- Hand over when ready. Invite the business owner into the books you set up; you keep your accountant access.
- Free while in beta, like the rest of Sumi.
