How to compare total postage costs for Shopify orders in Ireland

Build a monthly basket of the domestic orders you expect to send. Count the parcels in each packed weight band, then use those counts for every option. A mixed basket needs a subtotal for each band before you add the monthly fee.

• Weigh each parcel with its packaging.
• Record the number of parcels in each weight band.
• Enter the rate available to your account for each band.
• Add the subscription fee and any billed weight adjustments.

For occasional orders, calculate the cost for the month in which you would pay the subscription. A calculation based on a busier month can spread the fee across more labels than you actually buy.

To calculate how much postage your shop pays, subtract the shipping money collected from customers from the total postage expense. Record that result alongside the full expense.

EirPost publishes domestic label prices for parcels up to 2 kg, with An Post tracking included.

EirLink describes discounted rates on Plus and the first three labels of a free account, followed by retail rates.

EirPost lists Plus at €19 a month for unlimited labels and bulk processing, and requires Irish business verification for access to wholesale An Post rates.

Enter your agreed An Post rate if you already have a business account. For prepaid labels, enter the discounted or retail rate available to that account. Add the subscription only to the option that requires it.

For the free-tier calculation, confirm the initial allowance before counting a saving. Use the stated retail prices for later labels where a price is available.

A complete free-tier total for a mixed basket needs the retail rate for every weight band in that basket. The figures above supply retail prices for the lightest and heaviest bands. Leave the other retail subtotals uncalculated until you have the rates for your account.

1. Choose the account route and record its rates.
2. Complete business verification before budgeting for wholesale prices.
3. Calculate the label subtotal for your monthly basket.
4. Add the subscription fee where it applies.
5. Record prepaid top-ups separately from the labels charged to the balance.

A top-up moves money into your shipping balance. Count the label deductions as postage expense, then track the remaining balance as money already paid into the account.

Among the prices PostCompare compares, An Post’s cheapest bookable domestic price was €12.25 for a 1 kg parcel and €14.98 for a 2 kg parcel, both with 3–5 days delivery, in prices checked on 5 October 2026.

The worked totals below use the published discounted label rate plus the €19 monthly fee. They assume your account qualifies for that rate, every parcel stays within the stated band and there are no billed weight adjustments.

Multiply the parcel count by the rate available to your account, then add the monthly fee. For the separately bookable option, multiply the same parcel count by its dated price. For mixed weights, add the band subtotals before applying the fee.

Use domestic parcel prices to compare the weights in your own basket.

Buy the prepaid label online, print it at home and hand the parcel in at a post office. The published domestic label offer includes An Post tracking and supports a 4x6 thermal label.

Choose the weight band using the packed parcel. Round up when in doubt, as the label service’s help guidance advises. A later deduction for a heavier billed band increases that order’s postage cost.

Record the original label charge against the order. Add any later weight deduction to the same record, then update the monthly subtotal. Use the final charges when calculating your next basket.

Check the remaining prepaid balance before buying another batch. A failed label returns money to the balance, so match that credit to the failed order before calculating the month’s expense.
