Invoicing for Small Business: Setting Up Your Process
By the BePaid team · Updated · 4 min read
Short answer
A good small business invoicing process comes down to five decisions: a consistent invoice template, a numbering scheme, standard payment terms, a routine for sending and following up, and one place where you track what's paid, unpaid and overdue. Set these up once and every invoice after that takes a few minutes.
Step 1: Pick a template and fill in your details once
Choose one invoice layout and use it for every client. Add your business name, logo, address, phone and email. Save your common services with standard descriptions and rates so you're not retyping them each time. Browse the invoice templates or start with the professional invoice template. If you're unsure what fields you need, check what to put on an invoice.
Step 2: Choose a numbering scheme
Pick a format and stick with it. A year-based format is easy to sort and read.
Invoices: 2026-0001, 2026-0002, 2026-0003 … Quotes: Q-0001, Q-0002 … Credit memos: CM-0001 …

Step 3: Set standard payment terms
| Client type | Common terms | Notes |
|---|---|---|
| Homeowners and individuals | Due on receipt or net 7 | Send the invoice the day the job is done |
| Small businesses | Net 15 | Short enough to protect cash flow |
| Larger companies | Net 30 | Ask whether they need a PO number or W-9 first |
| Big or long projects | Deposit + progress billing | Don't finance the whole job yourself |
Put your terms in your quote or contract so they're agreed before work starts. If you want a late fee, it has to be agreed upfront and stay within your state's limits. The payment terms guide explains each option.
Step 4: Create a sending routine
- Invoice as soon as work is done, or on a fixed day for monthly clients.
- Send a PDF by email (or text for individual customers) with the invoice number, amount and due date in the message.
- Put a follow-up on your calendar for the day after each due date.
- Keep your reminder emails as saved drafts so following up takes seconds.
Step 5: Track what's paid
This is where many small businesses slip. Keep one list of every invoice with its status. A spreadsheet works; an invoicing app works better once you have more than a handful of clients.
| Invoice | Client | Amount | Due | Status | Paid on |
|---|---|---|---|---|---|
| 2026-0040 | Oakline Coffee Co. | $1,250.00 | Oct 31 | Paid | Oct 24 |
| 2026-0041 | Harbor Dental | $1,040.00 | Oct 15 | Overdue | — |
| 2026-0042 | Mesa Property Group | $675.00 | Nov 2 | Unpaid | — |
Review the list weekly. Anything overdue gets a reminder; anything paid gets recorded in your books.
Step 6: Keep good records
- Save a PDF of every invoice you send, in one folder or app.
- Record the date and method of each payment.
- Keep receipts for business expenses alongside your invoices so income and costs are in one place.
- Know whether you charge sales tax. Rules vary by state, and many states don't tax most services, so check your state's rules.
- Ask a tax professional how long to keep records and what your business needs to report.
Invoices, receipts and quotes: know the difference
Quotes and estimates come before the work and don't request payment. Invoices request payment. Receipts confirm payment was made. Keeping them in separate numbered series makes your records much easier to follow. For more, see what is an invoice.
Tools to run the process
The free invoice generator is a quick way to draft an invoice in your browser with no signup; the draft is saved on that device. For day-to-day invoicing, the BePaid iPhone app keeps clients, saved items, quotes and invoices together, marks each invoice paid, unpaid or overdue, scans expense receipts and shows reports. Your first invoice in the app is free. The app doesn't import drafts from the website, so set up your details there directly. For trade-specific setups, see the invoice generator for contractors or for landscapers, and the contractor invoice template.
Put this into practice
Create an invoice free on the web, then finish it in the BePaid app.
Frequently asked questions
What's the easiest way for a small business to start invoicing?
Pick one template, choose a numbering scheme and standard payment terms, and keep a single list of every invoice and its status. Everything else builds on that.
Can I just use a spreadsheet to track invoices?
Yes, especially early on. Track the invoice number, client, amount, due date, status and date paid. An invoicing app saves time as volume grows.
Do I need to charge sales tax on my invoices?
It depends on your state and what you sell. Many states don't tax most services. Check your state's rules or ask a tax professional.
How often should I review unpaid invoices?
Weekly works for most small businesses. Follow up on anything past due and record anything that's been paid.
