DueTab is the offline-first invoice maker, cash book and expense tracker built for small businesses, tradespeople, workshops, service teams and freelancers. Stop chasing paper notebooks, screenshots of receipts and forgotten payments. See exactly who owes you, who you owe, and where your money went, from one simple mobile ledger that works with or without a signal.

WHY BUSINESSES SWITCH TO DUETAB
Track every customer, job, invoice, payment and product in one place, back it all up to the cloud, and get paid faster with real invoices instead of a handwritten total on a scrap of paper.

WHO IT'S FOR
Tradespeople and repair or technical-service teams, workshops that build or install to order, retailers and wholesalers, freelancers and consultants, and any small business that outgrew a paper ledger but doesn't need, or want to pay for, full accounting software.

CONTACTS: RECEIVABLES & PAYABLES IN ONE SCREEN
See who owes you and who you owe on a single contact card, each with its own running balance. No more separate notebooks for money coming in and money going out. DueTab is a receivable and payable tracker in one, so your books stay honest on both sides.

INVOICES, QUOTES & RECEIPTS THAT LOOK THE PART
- Create real numbered invoices (INV-2026-001…) with due dates
- Convert a quote to an invoice in one tap, keeping every line item
- Add line items with quantity, unit price and totals, so there's no more single-total guesswork
- Choose from a library of branded invoice, quote and receipt templates, switch instantly, synced across every device
- Every document is saved for good and searchable, so you can follow it from draft to sent to paid

TRACK BILLS YOU OWE, NOT JUST BILLS YOU SEND
DueTab's debt tracker logs every bill you owe: record partial payments, set due-date reminders, attach the receipt, and let DueTab post the expense automatically. Never lose track of a supplier bill again.

CASH BOOK, BANK & WALLET ACCOUNTS
Keep a cash drawer, a bank account and a digital wallet side by side, each with an automatic running balance. Check your daily cash summary and know your cash position at a glance.

LET AI HANDLE THE DATA ENTRY
- Receipt scanner: snap a photo and DueTab reads the vendor, amount, tax and date for you
- AI bulk import: hand it any document (a photo, PDF or Excel file) and watch clean records appear automatically
- Home-screen quick actions get you into a new job, expense or invoice in one tap

CUSTOMER & JOB CRM
Keep customer details, phone numbers, addresses, job history, measurements and notes organized. See what's waiting, in progress, delivered or paid from one screen, without scrolling back through old chats to remember what was agreed.

REPORTS THAT ANSWER "HOW AM I DOING?"
- Profit & Loss (P&L) report
- Free custom date ranges plus period-over-period comparison
- Daily cash summary
- Export any report to Excel, CSV or PDF for your accountant

STOCK & INVENTORY, FOR PRODUCT AND WORKSHOP BUSINESSES
Log stock in and stock out for products, materials, spare parts and workshop supplies, link materials to jobs with a bill of materials (BOM), and get reorder alerts before you run out.

BUILT FOR REAL BUSINESS, NOT A DEMO
- Works fully offline: no signal, no problem, everything syncs the moment you're back online
- Multi-device cloud sync: start a job on your phone, finish the invoice on your tablet
- 27 languages, so your team can work in the language they're comfortable in
- No ads, ever

DueTab replaces the notebook, the group-chat full of receipt photos and the "I'll invoice them later" habit with one organized small-business bookkeeping ledger for customers, invoices, cash and stock, so you always know exactly where your business stands.
