Dartford know they'll have to play a waiting game in their bid to bring in more new players.
Callum Driver, Ben Greenhalgh and Kudus Oyenuga have joined the club this summer and seven members of the 2017-18 squad are staying on.
Joint-managers Adam Flanagan and Jamie Coyle are working on other signings but patience is going to be key.
Flanagan said: "We’re speaking to new targets and we’re waiting for them to come back and give decisions. Some of them have gone away so we’re communicating over the phone or waiting for them to come in.
"We’re not concerned. Hopefully we’ll get those answers in the next couple of weeks.
"If you’ve got a massive budget and can put a huge deal together, you might get a player to commit beforehand but normally at this time of year, players tend to go on holiday.
"They want a few weeks off and June is the time they start making decisions with regard to their football.
"We’ve not blanketed the market with regard to offers; we’re targeting players we feel can add value and make the team better.
"We’ve been quite specific with the players we’ve approached and we’re hoping we’ll get some decisions back this week or next.
"I still imagine we’ll leave room open within the squad for pre-season. I always feel, later on in pre-season, you tend to get players that have trialled at League clubs and then become available."
Duane Ofori-Acheampong, Tom Murphy and Richard Sho-Silva have all been invited back for pre-season.
Flanagan said: "Duane is a difficult one because he was contracted last season and missed a large portion (because of injury). We want reassurances that he’s over his injury.
"We’ve said to all three there’s a future at the club for them but we want to see improvements in the off-season and we’ll sit down and talk when we’re back during pre-season."
It's now exactly a month until Dartford's first friendly match, at home to Millwall on Saturday, July 7.
Flanagan said: "The way I look at pre-season, you play a lot of games quite quickly, Saturday-Tuesday, and in the first six weeks of the season you play about 12 games.
"You play a quarter of the season quite early so it’s going to be important we manage the load of the players during pre-season.
"We’ll probably run with a bigger squad during that time and look to cut that back the closer we get to the start."
