Huddersfield Town signed Tareiq Holmes-Dennis this week despite David Wagner's insistence the club was done in the market.
The boss has clarified he will be reactive rather than active in the market, and the signing of Holmes-Dennis was in reaction to Jason Davidson's loan move away from Town.
But how was the deal for the left-back done? What has to happen to get other deals over the line before the window slams shut on August 31?
Here's a step-by-step guide on how Town - and their rivals - go about signing players:
This usually starts months before the transfer window opens, with the scout not only reporting back on players' performances, but also forging relationships with clubs and agents in an attempt to get the inside track on their opposition.
The 'tapping-up' aspect of a scouts job is now arguably larger than watching potential signings, with more and more clubs using computer programs to build statistical analysis of players.
As well as this, the internet age has brought with it the ability for managers and directors of football to watch highlight videos of players within minutes of the full-time whistle.

Most of the bigger clubs use an online database of long-term targets which is updated regularly and they will move quickly when a player becomes available.
Once a player has been scouted and the management are impressed, the deal moves on to the next phase.
2. The bid
When scouting is complete, clubs will start the process of bidding for their target.
Although submitting an offer is easy, more ground-work is needed before the formal approach is made.
Article 18(3) of FIFA's Regulations on the Status and Transfer of Players states: "A club intending to conclude a contract with a professional must inform the player’s current club in writing before entering into negotiations with him."
This forbids the 'tapping-up' of players, but clubs bypass this by using trusted agents and third parties to gauge whether a player would be interested in signing.
Although supposedly illegal, this step is crucial as clubs do not want the embarrassment of being turned down by a target - which was the case when a Liverpool bid was rejected by Alexis Sanchez in 2014.
After a bid is accepted by the selling side, the next step of the process begins.
The negotiation stage of a transfer works on three different fronts:
- Negotiations between the clubs about the transfer fee.
- Negotiations between the buying club and the agent about the player's demands.
- Negotiations between the buying club and the agent about the agents' fees.
These negotiations can be short or long, depending on the needs of all parties. When transfers stall, it is usually because of wage demands or personal factors.
It takes skilled mediating to broker the best possible deal for both sides.
This point in the process is crucial as clubs that offer the best deals will pip their competition to signatures - such as when Paul Gascoigne chose Tottenham over Man United because the Londoners bought his parents a house.
4. Medical and work permit
Once everything has been agreed, players make their way to training facilities to undertake their medicals.
This is the point a signing becomes tangible for fans, but things can still fall apart at this stage.
Loic Remy failed a medical at Liverpool in 2014 and Demba Ba's move to Stoke collapsed at this stage in 2011.
The medical does not mean everything however, as Arsenal decided to sign Andrey Arshavin from Zenit St Petersburg after failing one medical and passing the second.
Receiving a work permit can also provide a stumbling block, as there are strict guidelines for being granted one.
Any player over the age of 16 who does not own an EU passport needs a permit, which the buying club will sponsor them for.
The FA receives the application and will grant the permit if the player has played 75% of competitive games for a FIFA-ranked top 70 nation over the previous two years.
After a medical is (or isn't) passed and work permit application is submitted, the player signs on the dotted line.
The paperwork is then normally faxed - yes faxed - to the league and the new man is thrown the club shirt and pictured around the stadium.
To give a rough scale from scouting to signing, for every 100 players watched, enquiries will be made for around 10 and only one or two will end up on the books.
