6 Apps for Small Businesses That Want to Sell Online Without Losing Track of the Numbers in 2026
6 Apps for Small Businesses That Want to Sell Online Without Losing Track of the Numbers in 2026
Online selling puts a business in front of customers well beyond its own neighbourhood, yet it also multiplies the numbers that need tracking. Orders come in at all hours, payment processors take fees before paying out, shipping costs differ from parcel to parcel, and sales tax depends on where each customer lives. If the store, the payment platform and the books are not talking to each other, stock counts drift, payouts fail to match sales and the true margin on each order turns into a guess.
Businesses that grow online without losing control maintain a clear line from every order to the accounting records. Each of their store, payment, shipping and customer tools does one job well and feeds accurate information into a single set of books. These six apps work well together to make that happen.
1. Sage 50: Accounting for Growing Small Businesses
Every online sale ends up in Sage 50, the accounting software. It records sales, tracks customer payments and supplier bills and reconciles bank statements to the books, so money landing in the bank can be matched to the orders behind it. GST/HST and PST/QST on sales are calculated too, and GST/HST returns can be filed online, which matters when orders ship to customers in different provinces.
With inventory built into the accounting, stock levels and inventory valuation update as sales are recorded, keeping the books aligned with what is on the shelf. More than 150 built in reports cover sales, sales taxes, inventory and profits, and cloud connectivity provides remote access to the company file, so the numbers are available wherever you work.
Why it matters: With sales, sales tax and inventory in one set of accounting records, each order adds to an accurate picture of revenue and margin.
2. Zapier: Automating Workflows Between Apps
Small gaps between apps remain even when the connections are good. Zapier links thousands of business applications using simple rules, for example sending a team alert when a large order comes in or adding new customers to a mailing list in your CRM.
Automating these small handoffs removes the copy and paste work that eats into an owner's day and leads to avoidable errors.
Why it matters: When handoffs are automated, every app stays up to date without anyone acting as the human link between them.
3. ShipStation: Managing Shipping and Order Fulfilment
For online sellers, shipping is among the easiest costs to underestimate. ShipStation brings in orders from your store and marketplaces, compares rates across carriers including Canada Post and prints labels in batches, helping orders go out faster and at a lower cost.
Holding shipment and label data in one place makes shipping costs easier to analyse by order, carrier or service, provided actual postage costs are captured accurately.
Why it matters: Knowing what shipping really costs is essential to knowing whether each online order actually makes money.
4. HubSpot CRM: Customer Relationships and Repeat Purchases
For an online business, repeat customers are usually the most profitable. HubSpot CRM records each customer's purchases and interactions and can connect to Shopify, so order history flows in automatically.
With that history gathered together, you can group customers by what they buy and how often, follow up with people who have not ordered for a while and see which products bring customers back.
Why it matters: Knowing who buys again, and why, helps you put marketing dollars where they earn the best return.
5. Stripe: Processing Online Payments
Stripe accepts credit and debit cards and other popular payment methods for businesses that sell through their own website or invoice trade customers, with fast payouts to the business bank account. Its reports break each payout down into individual charges, refunds and fees.
Reconciliation becomes straightforward with that breakdown, because sales can be recorded at full value and processing fees posted as an expense instead of quietly reducing revenue.
Why it matters: Clear payout reports turn a confusing deposit into a set of entries matching your sales.
6. Shopify: Building and Running Your Online Store
Many small businesses build their online store on Shopify, which handles product listings, checkout, discounts and order management together. It can run an in person point of sale as well, so online and in store sales share one product catalogue.
Once the store is connected to your accounting system, each order reaches the books with the customer, items, taxes and discounts already filled in, rather than being retyped from an order export.
Why it matters: As order volume grows, a store that feeds the books automatically keeps sales and stock records accurate.
Setting Up an Online Sales Stack
The stack works best when you set it up in three stages.
Get the books ready first: Create inventory items using the same product codes as your store, and set up tax codes for every province you ship to. Matching codes from day one is what allows later connections to post sales to the right items and tax accounts.
Connect sales, payments and shipping: Link the store to your accounting system, then bring in your payment processor and shipping platform. Run a few test orders and confirm each one records the right sale, tax, fee and shipping cost.
Review on a regular rhythm: Reconcile payment payouts each week, compare stock counts with your records monthly and review margin by product and channel every quarter. Add CRM and automation once the core numbers can be relied on.
Ecommerce Accounting FAQs
What sales tax applies to online orders shipped to other provinces? For GST/HST purposes, the place-of-supply rules generally look to where goods are delivered. Whether you must register for and collect GST/HST or a provincial sales tax, however, depends on the seller's circumstances and the applicable federal and provincial rules, and provincial taxes such as PST and QST have their own registration requirements. Sage 50 can track GST/HST and PST/QST tax codes, but your tax setup should reflect the registrations and obligations that actually apply to your business.
What is the right way to record payment processor fees? Record every sale at full value and post the processing fee separately as an expense, instead of recording only the net amount deposited. Revenue stays accurate, your sales tax reporting matches what customers actually paid, and you can see how much payment fees are really costing the business.
How frequently should online sellers count inventory? Plenty of small sellers count their fastest moving or highest value items each month and carry out a full count at year end. Comparing every count with the inventory reports in Sage 50 shows where shrinkage, returns or recording errors are creeping in, so they can be corrected before they distort your margins.
Should I sell on marketplaces as well as through my own store? Marketplaces can reach customers who would never find your website, but their fees, fulfilment requirements and return policies can cut deeply into margin. For a few months, track each channel's sales and costs separately before deciding how much of your range to list there.
