Method

• Products. Every bookkeeping product Tick Mark Books listed on 31 October 2026, 49 in all. We read each one's prices on the vendor's own pages. The date beside each is when we last checked.
• The month. 100 and 500 transactions a month. Each figure is the cheapest published plan that imports the bank and card transactions, categorizes them, reconciles the accounts each month and produces a profit and loss and a balance sheet, priced for a month at 100 and 500 transactions.
• The figure. The cheapest public plan that covers the month, with any charge for transactions past its allowance. It is in the vendor's own currency, as their page states it. A plan bought only through a sales call says "through sales".
• Dollars. The median, the cheapest and the most expensive compare prices in US dollars. Other currencies are converted at the European Central Bank rate: EUR 1.1172 on 30 October 2026 and GBP 1.3399 on 30 October 2026.
• Medians. The median is the middle figure. A category with fewer than 3 priced products gets no median, and one with fewer than two gets no cheapest or most expensive. A product in two categories counts in both.
• No price. A product with no public price for that many transactions is listed, but not counted or ranked.
