Email support
The address is support@zplempdf.com, and it covers everything: a question about a conversion, a label that came out wrong, billing, cancellation, a refund request, and privacy requests under the LGPD.
For a conversion problem, what helps most is where the file came from (which carrier, platform or system produced it), what appeared on screen and what you expected instead. You do not need to attach the label — it usually carries your customer's details, and we receive that content nowhere else in the product. If an attachment is the only way to reproduce it, send a test label.
Response times
Paid plans get an answer within 1 business day. A business day is Monday to Friday, excluding Brazilian national holidays, in Brasília time; the commitment is a reply from a person inside that window, not necessarily a finished fix.
The free plan carries no promised window, and messages still get read and answered — most of them the same day.
Billing, refunds and cancellation
Any charge can be refunded in full within 7 days, renewals included. Write and ask; we do not ask why. After that, cancelling ends the subscription at the end of the period already paid for, with no pro-rata refund.
Cancelling, changing plan or updating a card can also be done without us, from the account page, which opens Stripe's billing portal. If account access is itself the problem, write from the email address used at checkout.
Volume, API and integration
Operations that need more than a browser can hold — ERP integration, a dedicated API with agreed limits, a contract — are handled case by case on the Enterprise plan, which has a direct WhatsApp channel alongside email. The button at the foot of this page opens it.
The hosted API is not public yet. When it ships, the key comes with the paid plans, and this site will say so on the API section rather than promising it beforehand.
Where we are
ZPL em PDF is operated from Brazil by an independent developer, and support is answered in English, Portuguese and Spanish. There is no office to visit and no support phone line: the address above is the main channel, and it is the same one for legal and data-protection matters.
