Online Invoicing vs. Word or Excel Templates: When to Switch
In brief
A Word or Excel template is fine while you send a few invoices a month. Switch to online invoicing when you send more than about five invoices a month, chase late payments, bill clients on a schedule or invoice in several currencies. Many tools start free, so the switch costs little.

A Word or Excel invoice template is enough while you send a handful of invoices a month to a few regular clients. Switch to online invoicing when you send more than about five invoices a month, when you start chasing late payments, when you bill the same clients on a schedule, or when you invoice in more than one currency. At that point the time you spend typing, numbering and tracking invoices by hand costs more than invoicing software, which often starts free.

This article compares both approaches honestly, shows the signs that it is time to switch, and gives you a simple plan for moving your invoices out of spreadsheets without losing anything.

Why templates are a good place to start

There is nothing wrong with starting out with a template. If you just registered your business and have two clients, a well-designed template in Word, Excel or Google Docs gets you paid without signing up for anything. Templates have clear advantages:

  • They are free and you already have the software.
  • You control the layout completely.
  • There is nothing new to learn.

If that is where you are, you can download our free Microsoft Word invoice template or Google Docs invoice template, or browse other invoice templates.

Where Word and Excel templates start to cost you

The problems with templates do not show up on the first invoice. They show up on the fiftieth.

Numbering mistakes

Invoice numbers must be unique and sequential in most countries. With a template you copy last month's file, change the number and hope you did not skip or repeat one. A duplicated number is easy to make and painful to fix with your accountant or tax office.

Retyping the same details

Every invoice repeats your client's name, address and tax number, and your product names and prices. Each time you type them is another chance for a typo, and another few minutes gone.

No idea who has paid

A folder of PDFs does not tell you which invoices are overdue. Most template users end up keeping a second spreadsheet to track payments, and it is rarely up to date. Late payments slip through, and following up becomes awkward because you are not sure of the amounts and dates.

Tax calculations by hand

Excel formulas break when someone inserts a row, and Word does not calculate anything. If you charge VAT or sales tax at different rates, every manual calculation is a risk.

Clients abroad

Invoicing in euros, dollars and pounds with a template means separate files per currency and language, and manual exchange-rate work.

Your invoices live on one laptop

Template files sit on one computer or in a shared folder. When you are on the road and a client needs an invoice now, you have to wait until you are back at your desk.

Seven signs it is time to switch

  1. You send more than about five invoices a month.
  2. You have had to fix a wrong invoice number or a calculation error.
  3. You regularly chase clients for payment, or you are not sure who has paid.
  4. You bill some clients the same amount every month.
  5. You have clients in other countries or currencies.
  6. Someone else, such as a partner, an assistant or your accountant, needs access to your invoices.
  7. You want clients to pay by card or PayPal directly from the invoice.

If two or more of these sound familiar, online invoicing will almost certainly save you time from the first month.

What does the switch actually cost?

Less than many business owners expect. A lot of invoicing tools have a free plan for very small volumes. InvoiceOcean, for example, lets you send 3 invoices every month for free, and paid plans with unlimited invoices start at $9 (or £6 in the UK) per month billed yearly. Every paid plan can be tested free for 30 days, without a credit card. See the full comparison on the pricing page.

Compare that with the time saved. If you send 20 invoices a month and save just five minutes on each, plus an hour of payment tracking, you get back around two and a half hours every month.

How to move from templates to online invoicing

Moving is simpler than it looks. You do not need to migrate years of PDFs; you only need to continue from where you are.

  1. Create an account and add your company details and logo.
  2. Continue your numbering. Set the next invoice number to follow your last template invoice, so the sequence stays unbroken.
  3. Add your active clients and products. Start with the clients you bill most often; the rest can be added as you go.
  4. Send your next invoice from the software and keep your old PDFs archived for your records.
  5. Turn on online payments and reminders so new invoices are tracked from day one.
  6. Set up recurring invoices for clients you bill on a schedule.

When a template is still the right choice

To be fair, there are situations where a template remains a sensible choice: if you invoice once or twice a year, if you only ever bill one client, or if you need a one-off invoice for a private sale. In those cases a good template is perfectly adequate. For everyone else, the question is not whether to switch, but how soon.

Checklist before you switch

  • Note your last invoice number so the new sequence continues from it.
  • List your active clients with their full details and tax numbers.
  • List your products or services with prices and tax rates.
  • Collect your logo and payment details.
  • Decide which payment provider you want to connect, for example Stripe or PayPal.
  • Agree with your accountant how they will receive your invoices or reports.

Frequently asked questions

Is it OK to make invoices in Word or Excel?

Yes. A Word or Excel template is legally fine as long as the invoice contains all required details and the numbering is unique and sequential. It becomes impractical when you send many invoices or need to track payments.

When should I switch from invoice templates to invoicing software?

Switch when you send more than about five invoices a month, when you chase late payments, when you bill the same clients regularly or when you invoice in more than one currency.

Is online invoicing software expensive?

Not necessarily. Many tools have a free plan. InvoiceOcean lets you send 3 invoices a month for free, and paid plans with unlimited invoices start at $9 or 6 pounds per month billed yearly.

Can I keep my invoice numbering when I switch?

Yes. Set the next invoice number in the software so it continues from your last template invoice, and keep your old PDFs archived.

Is online invoicing secure?

Reputable invoicing software stores data on secure servers with SSL encryption and protects your account with a password. Some plans also let you limit access to selected IP addresses.
