Fair usage, without surprise billing
Plans should follow your growth, not punish your peaks.
Choose a plan around your normal monthly volume. If Christmas, a campaign or a strong month pushes you temporarily above the allowance, your workflows keep running.
Your busiest month does not define your plan.
We do not automatically charge for the excess or bill previous peaks retrospectively. If your normal usage consistently and materially outgrows the plan over time, we will contact you before asking you to move to a more suitable plan for a future billing period.
One order means one order
Customer matching, product matching and the Sellsy document do not turn one ecommerce order into several usage units.
Seasonal peaks are fine
A busy Christmas, campaign or launch does not trigger an immediate plan change or interrupt your workflows.
No surprise overage bills
Temporary excess usage is not turned into an unexpected invoice and previous peaks are not billed retrospectively.
Upgrade when growth is sustained
If your normal usage materially outgrows the plan over time, we contact you before a future plan change.
Included from Starter
€39Stock synchronization should not be reserved for higher-tier plans.
For Shopify, PrestaShop and Wix, Starter includes Sellsy → ecommerce stock synchronization. Stock is a day-to-day ecommerce need, so we include it from €39 wherever the connector supports it.

Monitoring
Follow workflow activity and understand whether transfers completed.
Logs and failure context
See failed transfers and the context needed to investigate them.
Manual recovery
Replay supported workflows after the underlying issue is corrected.
Workflow configuration
Use mappings and settings tailored to each connector and the capabilities its platform actually supports.

Orders and credits are not the same thing
Synchron counts one ecommerce order as one usage unit. Order Invoicer measures usage in credits consumed by synchronized objects, so the two allowances cannot be compared one-for-one.

Frequently asked questions
Questions before you connect
Which Sellsy integrations qualify for Free and Starter?
Shopify, WooCommerce, PrestaShop and Wix with Sellsy qualify. HubSpot + Sellsy starts on Standard because it covers broader CRM and business-process workflows.
What do I get on Starter for €39 per month?
Starter is the complete standard Sellsy ecommerce offer for stores that normally process up to 300 orders per month. It includes the ready-made workflows available for your connector, monitoring, logs, recovery tools where supported, standard mappings, email support and stock synchronization where the connector supports it.
What counts as an ecommerce order?
One ecommerce order counts as one order. Customer and product matching, the associated Sellsy document and internal workflow records do not turn that order into several usage units. Related refund and stock workflows are not counted as extra ecommerce orders.
What happens if I temporarily exceed my plan allowance?
Your integrations keep running and there is no automatic overage charge. Monthly allowances describe the normal usage a plan is designed for, so seasonal campaigns and occasional busy months are fine. Previous peaks are not billed retrospectively.
Do I need to upgrade after one unusually busy month?
Usually not. We look at sustained normal usage rather than a single month. If your business consistently and materially outgrows the plan over time, we will contact you before asking you to move to a more suitable plan for a future billing period.
What if I normally process a little more than 300 orders, for example 320 or 350?
Starter does not suddenly stop at order 301. If your normal volume stays close to the Starter allowance, occasional or modest excess usage is fine. Standard becomes appropriate when your sustained volume or workflow requirements genuinely move to the next level.
Does stock synchronization work on Starter?
Yes, from Starter where the connector supports it. It is currently available for Shopify, PrestaShop and Wix with Sellsy. WooCommerce + Sellsy currently focuses on order-to-invoice automation.
How is the 30-day trial different from the Free plan?
The 30-day trial lets you validate the complete Sellsy ecommerce experience with your own data. After the trial, very small stores can continue on Free within the 100-order normal monthly allowance, while growing stores can choose Starter or a higher plan.
Is HubSpot + Sellsy available for €39?
No. HubSpot + Sellsy is a broader CRM and sales-process integration, so it is not eligible for Free or Starter and starts on Standard at €150 per month.
Are refunds and credit notes supported?
They are included where the actual connector supports them. Shopify and PrestaShop currently document refund-to-credit-note workflows; workflow coverage is shown on each connector card and integration page.
Can I upgrade later?
Yes. Free, Starter, Standard, Advanced and Custom use the same Synchron platform, so you can add capacity and more advanced options without migrating to another integration product.
Can I pay yearly?
Yes. Yearly plans include two months free: Starter is €390/year, Standard €1,500/year and Advanced €3,500/year.
Do all four ecommerce connectors support exactly the same workflows?
No. Shopify, WooCommerce, PrestaShop and Wix expose different capabilities. The connector cards and full integration pages show the workflows currently available for each pair.
Connect your store to Sellsy free for 30 days.
Validate the workflows with your own data. Then stay on Free if your store normally processes up to 100 orders per month, or choose the plan that matches your business.
