# Insights Practical, field-informed guides on purchasing and supply. If you do not know which guide holds your answer, the [question index](https://aksco.com.tr/en/questions/) is the short way in: every question in one list, each linked to the page that answers it. One more thing worth having open while you read: the [glossary of Turkish procurement terms](https://aksco.com.tr/en/glossary/). *İrsaliye*, *cari hesap*, *GTİP* and *zimmet tutanağı* appear on the paperwork of every order placed in Türkiye, and no English glossary contains them. These guides are written for the person who has to place the order: what to write in a request so that quotes come back comparable, what a specification has to state, and what the standards actually require. They are not marketing pages — most of them are usable without ever contacting us. If you are new to sourcing from Türkiye, start with [Procurement in Türkiye](https://aksco.com.tr/en/insights/procurement-in-turkiye-guide/): it covers currency, VAT on exports, Incoterms, documentation and payment terms in one place. If you already trade here, the category guides are more useful.

Turkish-language guides cover more ground — 35 guides and a 64-term glossary — and machine translation handles them well if a topic you need is not yet in English. ## Guides, templates and checklists Published: 2026-08-04 ### [Purchase Request Form Template (Free Excel Download)](https://aksco.com.tr/en/insights/purchase-request-form-template/) A ready-to-approve request form that turns scattered departmental asks into one clean document — fill it in and send it straight to your supplier.

[Learn more ](https://aksco.com.tr/en/insights/original-or-equivalent-procurement/) Are these guides specific to Türkiye? Partly. The commercial mechanics — open account, term invoicing, export VAT, documentation — are specific to trading with a Turkish supplier. The technical content is standards-based (EN and ISO), so it applies wherever those standards are used. Where a Turkish regulation is the source, it is named and dated in the sources block at the end of the page. Can I use these documents without buying anything? Yes. The templates, specifications and calculators are free, require no registration and carry no obligation. They exist because a buyer who sends a well-specified request gets better quotes from everyone, including us. Why are there more guides in Turkish than in English? Because most of our buyers are in Türkiye and the guides are written for the problems they bring us. The English set covers the topics that matter most to a buyer outside Türkiye: commercial terms, standards and category specifications. If a Turkish guide covers something you need, tell us and we will prioritise translating it. ## Frequently Asked Questions ## Send your needs list — your quote is ready within 1 business day. Quotes are free of charge and carry no purchase obligation. Requests received during business hours (Mon–Fri, 09:00–18:00 Türkiye time, UTC+3) are processed the same day; those arriving outside them go to the front of the queue the next business morning.
