Manager John Sheridan has promised Welling United will be taken "very seriously" when Plymouth Argyle play them in the FA Cup second round at Home Park today.
At stake is £27,000 in prize money for the winners, plus a place in round three and the possibility of a lucrative tie against Premier League opposition.
There are 20 positions in the football pyramid separating Argyle, who are 16th in League Two, and part-timers Welling, who are 13th in the Conference Premier.
The Pilgrims will start as firm favourites, but Sheridan is not taking anything for granted.
He said: "It's a massive game for us and I expect it to be very tough. We have had them [Welling] watched and they have got some decent players.
"We will take the game very seriously. It's important we get through to the next round, both financially and for the chance to play against really good opposition."
Sheridan has seen a DVD of Welling's 2-1 defeat at Luton Town in the Conference Premier on November 23.
"They were unfortunate to lose at Luton a couple of weeks ago," said the Pilgrims' boss.
Argyle had been unbeaten in eight games in all competitions until last Saturday when Burton Albion came away from Home Park with a 1-0 win in League Two.
Sheridan said: "I thought we were excellent against Burton, no matter what anyone says. Everyone just looks at the result, but I have seen the DVD and I thought we were excellent. We will try to take that form into the [Welling] game and if we do that we will have a good chance of winning."
Argyle beat Welling's Conference Premier rivals Lincoln City 5-0 in a FA Cup first-round replay at Home Park last month, scoring two goals in the opening five minutes.
Lincoln never recovered from that, and Sheridan hopes his side can make another positive start against Welling.
Sheridan said: "It helps in any game if you get the opposition on the back foot early, and you get that break and score a goal.
"Then the opposition usually have to come out and try to get back in the game.
"Hopefully, we can hit the ground running. If we can do what we did against Lincoln I will be well pleased, but you have got to earn the right, no matter who you are playing.
"We will hopefully start on the front foot and try to get an advantage early on in the game.
I would love a great performance, but the most important thing is getting through the tie. We know what's at stake, financially, and it's always nice to be in the FA Cup and the buzz it brings with it.
"Welling will come and I think they will have a really good go, and we have got to be ready for that. Hopefully, we can deal with it. It's important we start the game well and get them on the back foot."
