Small‑business expense tracking — starter system, categories, tools, and real templates

I’m gathering a short, practical starter guide + community clinic for micro/small businesses that need a simple system to: capture receipts, classify spending, reconcile accounts, support tax claims, and handle employee reimbursements. I’m not offering professional advice — I want this thread to collect first‑hand workflows, templates, and tool recommendations from people who run or support small businesses.

Quick suggested starter system (one page you can adopt today):
- Capture: photo of receipt immediately (mobile app or camera). Save a PDF copy for invoices.
- Tag: add vendor, date, purpose, project/client, and tax tag (deductible vs non‑deductible).
- Sync: attach to bank/credit card transaction or mark as reimbursable. Auto‑import bank feeds daily.
- Reconcile: weekly quick review; monthly full reconciliation (bank, cards, outstanding reimbursements).
- File: keep receipts for 7 years (or local legal requirement); export monthly P&L for accountant.
- Reimburse: submit receipts within X days, manager approves, payment processed on next payroll or expense run.

Starter expense categories (minimal, tax‑friendly):
- COGS / Materials
- Office supplies
- Advertising & marketing
- Travel
- Meals & entertainment (note business meal rules)
- Subscriptions & SaaS
- Professional fees (accountant, lawyer)
- Rent & utilities
- Payroll & contractors
- Equipment / capital expenditures
- Vehicle / mileage
- Bank fees & interest
- Licenses & taxes
- Employee reimbursements (track separately)

Questions for people with real experience — please answer any you can:
1) One‑sentence workflow you actually use (example: “Photo → app OCR → categorize → weekly reconcile”)
2) Which categories you find essential, and any category mapping you use for QuickBooks/Xero?
3) Favorite inexpensive tool(s) for receipt capture + bookkeeping (price tier, mobile OCR accuracy, bank sync).
4) Reimbursement policy you use (per‑diem vs receipts, submission deadline, approval steps). Paste an anonymized template if possible.
5) Monthly reconciliation checklist items you run before closing books.
6) Biggest pain you solved (duplicate receipts, missed deductions, messy reimbursements) and how you fixed it.

If you can, please share: short screenshots (remove PII), a simple Google Sheet or CSV example of your categories, or a one‑page reconciliation checklist. If you prefer, post just one tip that saved you time or money.

I’ll compile top answers into a concise downloadable checklist and a short “starter category list” that everyone can copy. Thanks — looking forward to real workflows and templates from people who do this every day.
