Below are the six jobs an online store has to get right, with three tools to consider for each. Start with a card for ads and suppliers: Wallester's free plan includes 300 virtual cards, enough for each ad platform and supplier to have its own.

What online retail need, and the tools that do it

This is general information, not financial or legal advice. Tools are listed by how well they fit the job, and some links may earn us a commission.

Paying for ads and suppliers

Ad platforms and suppliers charge you before your customers pay you. Separate cards for ads, stock and software make spend easy to track and cap the damage from a bad charge.

What to look for

  • Virtual cards you can create instantly
  • Limits per card
  • Receipts that sync to your accounting

Our picks

  • Wallester Business

    Free plan with 300 virtual cards, so ads, suppliers and software can each have their own.

  • Ramp

    US card and spend platform with a free plan, aimed at US businesses.

  • Pleo

    Receipt capture and spend controls for teams in Europe, priced per user.

Receiving marketplace and processor payouts

Marketplaces and payment processors pay out in the currency of the sales channel. Converting at a bank's rate on every payout adds up.

What to look for

  • Local account details in your sales currencies
  • Clear conversion pricing
  • Easy transfers to your main account

Our picks

  • Wise Business

    Local account details in several currencies and conversion at the mid-market rate.

  • Airwallex

    Collection accounts in several currencies for businesses selling across borders.

  • Revolut Business

    Several currencies and cards in one business account.

Bookkeeping, stock and sales tax

Sales tax, returns and stock levels make retail books messier than most. Pick software that connects to your sales channels and that your accountant can work in.

What to look for

  • Connections to your sales channels
  • Sales tax or VAT handling
  • Stock tracking if you hold inventory

Our picks

  • Xero

    Many e-commerce and inventory apps connect to it, and it handles several currencies.

  • QuickBooks

    Tracks sales tax and is widely supported by US accountants.

  • Zoho Books

    Includes inventory tracking and connects to the rest of the Zoho suite.

Funding stock between payouts

Buying stock ahead of a busy season can outrun your cash. Short-term credit can bridge that, but it has a cost, so borrow only against a clear plan to repay.

What to look for

  • Clear total cost, not only the headline rate
  • Repayment that follows your sales cycle
  • No penalties for paying early

Our picks

  • Bluevine

    US lines of credit for small businesses.

  • Fundbox

    US credit tied to your outstanding invoices.

  • Lendio

    US marketplace that matches you with several lenders from one application.

Hiring help and paying freelancers

Seasonal peaks mean temporary staff, and customer service or design is often outsourced to freelancers abroad.

What to look for

  • Payroll that handles part-time and seasonal staff
  • Contractor payments in other currencies
  • Contracts that suit the contractor's country

Our picks

  • Gusto

    US payroll with tax filing and contractor payments.

  • Deel

    Contracts and payments for contractors and employees in many countries.

Covering product and liability risk

If a product you sell causes harm or damage, claims can reach you as the seller. General and product liability cover is a common requirement from marketplaces and landlords.

What to look for

  • Product liability included
  • Cover that matches the products you sell
  • Limits that suit your sales volume

In depth

How money moves through an online store, and how to keep control of it

The money flow of an online seller

Online sellers pay suppliers and ad platforms first, then collect from customers through card processors or marketplaces, usually after a delay. Each channel takes fees, holds reserves for returns and pays out on its own schedule. The result is that profit on paper and cash in the bank are often far apart.

Keep separate pots of money

  • An operating account that receives payouts and pays suppliers.
  • A tax pot, so sales tax or VAT collected is not spent.
  • A dedicated card for each ad platform, so spend is capped and traceable.
  • A reserve for refunds and chargebacks.

Payouts in several currencies

Marketplaces and processors pay out in the currency of the sales channel. Receiving into an account that holds that currency, and converting when it suits you, usually costs less than letting each payout convert at a bank's rate. Compare the total cost, not only the headline rate.

Sales tax and VAT

Rules vary widely. In some countries and for some marketplaces the platform collects and remits tax for you, and in others you must register and file yourself, sometimes in several jurisdictions as you grow. Get advice early, and choose accounting software that records tax by region.

Inventory and cash

Stock is cash sitting on a shelf. Track what you hold, what it cost and how fast it sells, so you do not order more than you can sell. If you borrow to buy stock, compare the total cost and make sure repayments follow your sales cycle.

Common mistakes

  • Treating gross sales as profit and spending accordingly.
  • Ignoring fees, returns and ad costs when pricing.
  • Mixing personal and business money.
  • Missing registration thresholds for sales tax or VAT.
  • Over-ordering stock because last season was strong.
FAQ

Common questions

Put each ad platform on its own card with a limit, so one runaway campaign or compromised card cannot drain your account. Match the receipts to your accounting each month.

Use an account that gives you local account details in the marketplace's currency and converts at a transparent rate, instead of letting the payout convert automatically at a bank's rate.

If you hold stock, yes, or you risk misstating cost of goods sold. Check whether the tool tracks stock itself or relies on an app.

It can be if you have a clear plan to repay from sales. Compare the total cost, not only the interest rate, and avoid borrowing for stock you are unsure will sell.
