From enquiry to quote to invoice to payment, without five separate apps

An invoice records what someone owes. A payment service collects money. Bookkeeping records what happened. One tool may cover all three, but creating an invoice does not automatically give you free card processing, automated reminders, or reconciled books.

Start with the tools you already have. You need a clear agreement, an invoice reference, a way to pay, and a record that connects the payment to the work. Add another app only when a step is failing or taking enough time to justify it.

The workflow below works for Canadian and US businesses. Tax registration, invoice information, payment eligibility, and record retention depend on where your business operates and what it sells. Select those details for your situation before using the first invoice; choosing a Canadian or US software setting does not establish compliance.

1. Turn the enquiry into a defined job

Record the request in your lead list. Before quoting, confirm what the customer wants, where the work happens, who can approve it, and any date or access constraints. Write down the next action.

Use the simple lead follow-up workflow to keep the request and the next reminder connected before it becomes an invoice.

Use a stable job reference in your quote, invoice, messages, and payment notes. Customer names alone are a poor match when two jobs are running for the same person.

2. Quote the scope and the terms together

Your quote should make these items understandable:

Your business identity, contact details, quote reference, and date.
Customer and job details.
Included work or items, with meaningful quantities where applicable.
Exclusions and assumptions, such as customer-supplied materials or site access.
Amounts and currency, with taxes, discounts, and other charges clearly treated.
Validity period, proposed schedule, and what acceptance means.
Any agreed deposit and when it is due.
How changes will be priced and approved.
Payment timing and any other terms agreed before the work begins.

Do not hide a material charge in a later invoice. If scope changes, record the change and obtain approval before doing the extra work. Some industries and jurisdictions have additional contract or deposit rules; a simple layout does not replace them.

An approval request can say:

Please confirm that quote [reference], including [scope] and the attached payment terms, is approved by [authorized person]. If anything needs changing, reply before we schedule the work.

Save the approval with the quote version it applies to. “The customer said yes” without the accepted scope leaves room for a dispute.

3. Keep deposits and final invoices connected

If the agreement includes a deposit, record its invoice/payment reference separately and show how it is applied against the job. Avoid counting the deposit twice as new revenue or requesting the full amount again without showing the credit.

Before issuing the final invoice, compare it with the accepted quote and any approved changes. Include the invoice reference, issue date, customer/job details, currency, charges, applicable taxes, credits, balance due, due date, and payment instructions. Use unique references and retain the documents you actually sent.

Canada: GST/HST is one part of the check

Use CRA’s GST/HST guide to check registration, how tax is disclosed, and the supporting information a customer needs. Include your applicable tax registration details where required. The requirements depend on the sale and your registration status. Do not collect tax merely because a template contains a tax field, or label a sale exempt simply because you have not registered.

Check provincial sales taxes separately where applicable. For Quebec, Revenu Québec’s invoice guidance addresses GST/QST supporting information and points to additional billing rules for certain industries. A general invoice template does not resolve those requirements.

A US customer’s address does not automatically make a Canadian sale tax-free. For cross-border work, use CRA’s imports and exports guidance and get advice on your actual supply rather than copying another business’s treatment.

United States: use the relevant state and local authorities

Check whether your goods or services are taxable, where the sale is treated as occurring, whether your business must register, and which invoice details or exemption records are required. Sales-tax obligations vary by state and locality. A business connection to another state, often called nexus, can matter; SBA explains why physical or economic presence can create collection obligations. A service business should not assume all its work is tax-free.

Find the relevant agencies through USAGov’s state and local tax directory and follow their current rules. IRS federal recordkeeping guidance is useful for your books, but it does not answer which state sales tax to charge. A processor’s tax fields or a customer’s out-of-state address do not make that decision for you.

4. Offer a payment method that fits the customer

If you already invoice successfully in a bookkeeping tool, try that first. Wave’s current plan information separates its Starter invoicing/bookkeeping functions from paid features and online payment processing. Online payment approval has eligibility checks, including identity verification and credit review. Check whether the exact reminder or payment function you want is included before designing the process around it.

Wave supports businesses in Canada and the United States, excluding US territories. Its free invoicing functions are a possible starting point for those businesses, not a promise that every business will qualify for payment processing. Confirm supported business activities, bank accounts, currencies, and payout terms before offering checkout to customers.

For a manually delivered invoice, send a clean PDF or your tool’s supported invoice link and use your calendar for the due-date reminder. For online collection, see the payment-link guide. Match the invoice reference to the payment record. A new processor is not necessary merely because you create a new invoice.

Canada: Interac e-Transfer can fit domestic invoices where both parties can use the service. Interac’s business FAQ requires a Canadian online bank account with a participating bank or credit union. Check your bank’s business terms, limits, and fees. Do not promise this route to a US customer solely because you have their email address.

United States: card payments, checks, or provider-supported ACH bank payments may fit your customer. Nacha explains ACH as a US bank-payment network; it is not another name for Interac e-Transfer. Check customer and merchant account eligibility, authorization requirements, processing fees, and the expected payout date for your chosen method. Never label a method free without checking your own account.

For CAD and USD invoices, agree on the billing currency and record the payment currency. Check who bears conversion or processing charges. Keep amounts in separate currencies until your accounting process converts them deliberately. Adding CAD and USD balances into one “total owed” number is misleading.

Creating a foreign-currency invoice is different from collecting it online. Wave documents foreign-currency invoicing, but its Canadian payment-customer terms specify CAD payments and its US payment-customer terms specify USD payments. Before promising checkout in a different currency, verify the actual processor route and its applicable terms. If payment arrives through another method, use the foreign-currency payment procedure to record the payment and exchange rate without duplicating an imported transaction.

5. Follow up without losing the record

Download the Scout business workflows workbook and use its Invoices tab to record amount due, due date, received amount, payment reference, and reconciliation date. Enter received amounts in the invoice currency; keep any different bank-settlement currency and conversion details in your books. The tab distinguishes an overdue balance from a missing date and a received payment that still needs matching. It does not calculate sales tax, determine an exemption, or file a return.

For an approaching due date:

Hi [name], invoice [reference] for [job] is due on [date]. The invoice and payment instructions are here: [link]. Please let me know if you need a correction or have a question.

For an overdue invoice:

Hi [name], our records show a balance outstanding on invoice [reference], due [date]. If you have paid, could you send the payment date and reference so we can match it? Otherwise, please confirm when payment is expected.

Check your records before sending. Do not apply an unexpected late fee or automated threat that was never part of the agreement. A reminder is not a remedy for a genuine dispute about scope or quality.

If a payment is formally disputed

A customer’s complaint, a card chargeback, and a bank-payment return have different processes. Confirm the notice in the processor dashboard and record the deadline before continuing ordinary invoice reminders. Use the dispute response workflow and its evidence checklist to connect the original scope, acceptance, fulfilment, correspondence, and refund record to the specific claim. Do not fabricate missing acceptance or send a duplicate refund. Valid complaints need a resolution; disputed funds may be unavailable while the case is reviewed.

6. Reconcile and retain

Reconciliation means matching the invoice to money actually received. Use the bank or processor record, not a customer’s screenshot alone. Record gross payment, fees, refunds, and net deposit appropriately in your bookkeeping system. A processor deposit may combine several payments and subtract fees, so it may not match an individual invoice amount.

The tracker is an operational index, not a substitute for your books. Retain original invoices, approvals, credit notes, and supporting records. Canada: CRA describes GST/HST record retention; check applicable provincial requirements as well.United States: the IRS describes federal business recordkeeping; your state and local tax agencies may have additional requirements. Retention periods and exceptions depend on the records and business. Do not delete them when cancelling the app.

You are finished when: a test job can move from request to approval, invoice, verified payment, and a readable export without losing its reference or currency. Pay for automation when it reduces actual administrative work without obscuring that chain.
