How we issue invoices

CleanWhale operates as an intermediary platform (marketplace) that connects you with independent Contractors providing cleaning and other services.

CleanWhale issues you a VAT invoice only for the Order Handling Fee — our remuneration for intermediary services: selecting and verifying the Contractor, coordination, and handling documents and payments.

The service is provided and documented directly by the Contractor, who issues you a separate document for its full value: a VAT invoice if the Contractor is an active VAT payer (VAT deductible on your side), or an invoice without VAT or a bill if the Contractor is exempt (a tax-deductible cost, without VAT deduction).

You therefore receive two documents per order, and both are tax-deductible costs. Your final price and payment method stay the same.

How we calculate VAT

CleanWhale charges VAT only on its own remuneration, not on the value of the service — the seller of the service is the Contractor, not CleanWhale. Our invoice: the Order Handling Fee plus 23% VAT, fully deductible on your side. The Contractor's invoice: VAT depends solely on their status. There is no double taxation — VAT appears at most once on each side.

Window Adjustment, Repair, and Maintenance in Leszno and Surrounding Areas

Are drafty seals letting cold air into your home, or are handles jamming when you try to open the sash? Timely window adjustment, dependable window repair, and comprehensive window service in Leszno eliminate drafts and operational issues without requiring expensive replacements.

When Should You Schedule Window Adjustment in Leszno?

Regular maintenance ensures your frames remain energy-efficient, tight, and easy to operate year after year. Temperature swings, humidity, and constant daily use naturally loosen hardware fittings. Whether you live in central Leszno or nearby neighborhoods such as Daleszyn and Lubiń, routine care prevents costly frame damage.

We recommend booking a window service and adjustment if you encounter:

Cold drafts or outside air escaping through closed sashes,
The window sash scraping against the lower frame or sill during closing,
Stiff, clicking, or completely blocked window handles,
Uneven corner gaps that fail to pull tight,
Excess moisture or condensation gathering on the interior glass profile.

Proper seasonal calibration helps maintain low heating bills in winter and optimal micro-ventilation in summer.
