Fulfilment meaning
Fulfilment (or fulfillment) is a noun with three common meanings:
- Doing what was promised or required. The act of completing a promise, duty, request or condition. “The fulfilment of the contract took six months.”
- A feeling of satisfaction. Happiness that comes from achieving something or using your abilities fully. “She found real fulfilment in teaching.”
- Order fulfilment (business). The process of storing products, then picking, packing and delivering customer orders. “We outsourced our fulfilment to a warehouse in Poland.”
Synonyms: completion, achievement, realisation, satisfaction, contentment. Opposites: failure, disappointment, frustration.
Word origin: the verb comes from Old English fullfyllan, “to fill up completely”, from full and fyllan (to fill).
Common misspellings of fulfilment
Fulfilment is one of the most often misspelled words in English. The usual mistake is a double L at the start. These are all wrong:
| Wrong | Correct |
|---|---|
| fullfilment | fulfilment (UK) · fulfillment (US) |
| fullfillment | fulfilment (UK) · fulfillment (US) |
| fulfiment | fulfilment (UK) · fulfillment (US) |
| fufillment | fulfilment (UK) · fulfillment (US) |
| fulliment | fulfilment (UK) · fulfillment (US) |
| fulfillmet, fulfilmant | fulfilment (UK) · fulfillment (US) |
How to remember it: the word starts with ful, like beautiful or careful, never full. Then add fil (UK) or fill (US), then ment. UK: ful + fil + ment. US: ful + fill + ment.
Which spelling should you use?
- Writing for a US audience? Use fulfillment.
- Writing for the UK, Europe, Australia, India or Africa? Use fulfilment. The English used by EU institutions follows British spelling, so fulfilment is the usual choice for European businesses. That is why Waredock writes fulfilment.
- Writing for an international audience? Choose one, then use it everywhere: website, emails, invoices and product listings.
- Using a proper name? Keep the spelling the company uses, such as Amazon’s “Fulfillment by Amazon”, even in British English text.
Does the spelling matter for SEO? Search engines generally understand that both spellings are the same word. Readers notice, though, so match your audience and stay consistent instead of mixing both on one page.
What is fulfilment in eCommerce?
In eCommerce and logistics, fulfilment means everything that happens between a customer clicking “buy” and the parcel arriving at their door:
- A fulfilment centre (US: fulfillment center) is a warehouse built for this work: it ships many small orders every day, rather than just storing goods. See distribution centre vs fulfilment centre.
- A fulfilment provider or 3PL (third-party logistics provider) runs that work for online shops, so they don’t need their own warehouse. See 3PL vs in-house fulfilment costs.
- Picking is collecting the right items for each order from the shelves. See picking in our glossary.
